+# Augmented Reality Video Streaming over WebRTC
+
+The next generation of real-time streaming applications like video-conferencing apps will augment video streams that are generated and computed from the feed. Understanding computation overheads present in enabling such advanced features can inform scheduling strategies within the edge computing environments. This research project aims to explore the possibilities of distributing the components of WebRTC, the backbone technology for real-time video conferencing, across edge devices. We specifically focus on the analysis of the computational overheads associated with deploying augmented reality and FFmpeg filters in video streams.

+
+## Experimental Setup
+### Step1: Compile source code
+In the current directory, execute the below commands 
+```
+make clean
+make
+```
+
+### Step2: Start the signalling server
+```
+./bin/main --server
+```
+
+### Step3: Bring 2 clients into the system
+Start a client in two different terminals
+```
+./bin/main --client
+```
+
+### Step4: Start the AR-processing script
+```
+python3 ar-filters/app.py
+```
+
+### Step5: Start the video streaming source
+```
+ffmpeg -f v4l2 -i /dev/video0 -f mpegts udp://224.0.0.251:5353
+```
